Add and document PARKEDCALL variable set during timeout

PARKEDCALL variable tracks which parking lot the call was last parked in.  This can be
used afterwards for flow control when returntoorigin is set to off. I went ahead and
documented both this and the existing variable set during timeout (PARKINGSLOT) in
the sample features.conf since there was no prior mention of variables being set during
timeout.
